    Description: The invention relates to a ship voltage supply system or power station voltage supply system.
    Electric ships also play on ships e.g. for the hybridization of the drive system an increasingly important role. To operate electrical consumers of a ship, such as for example the operation of electrical machines that serve to propel the ship, electrical ship voltage supply systems are required in order to supply the electrical machine or the electrical consumer with a sufficient electrical voltage or sufficient electrical energy. There is a need for a ship voltage supply system that can provide a desired electrical target voltage and a desired electrical target energy to an electrical consumer of a ship with little effort and therefore at low cost. Comparable requirements also exist for stationary applications in power plants. Proceeding from this, the object of the invention is to create a new type of ship or power plant voltage supply system.
    This object is achieved by a ship voltage supply system according to claim 1. The marine voltage supply system according to the invention has a plurality of automobile traction battery modules, each automobile traction battery module having an electrical actual voltage and an electrical actual energy. The plurality of automotive traction battery modules are dependent on the target electrical voltage, the actual electrical voltage, the target electrical energy and the actual electrical energy in series connections to a plurality of traction battery module subgroups and / or in a parallel connection to at least one traction battery module group connected.
    With the present invention, it is proposed to use automotive traction battery modules in a marine power supply system, which are known from automotive applications in the automotive field. However, since such automotive traction battery modules differ in terms of their actual electrical voltage and / or actual electrical energy from the target voltage and / or the target energy of the ship's electrical consumer, the invention proposes a defined connection of the automotive traction battery modules. The invention makes it possible to provide, with simple expense and using automotive traction battery modules, a ship voltage supply system which supplies an electrical consumer of the ship, for example an electrical machine serving to propel the ship, with a desired electrical target voltage and electrical target energy ,
    Then, when the actual electrical voltage of the automotive traction battery modules corresponds to the target electrical voltage of the electrical consumer, a plurality of automotive traction battery modules are connected in parallel to at least one traction battery module group. Then, when the actual electrical voltage of the automotive traction battery modules is less than the target electrical voltage of the electrical consumer, a plurality of automotive traction battery modules are connected in series to a traction battery module sub-group and a plurality of traction battery module sub-groups are connected in parallel to at least one traction battery module group. Such an electrical connection of the automotive traction battery modules is preferred in order to supply the electrical consumer of the ship with the electrical target voltage and electrical target energy.
    Preferably, the automotive traction battery modules can be controlled via an automotive CAN bus system. This enables the automotive traction battery modules to be controlled with little effort and using automotive CAN bus systems. In this way, a simple and inexpensive ship voltage supply system can be provided.
    According to a further development, the ship's voltage supply system has several traction battery module groups connected in parallel, the number of automotive traction battery modules per traction battery module group being dependent on the control signal capacity of the automotive CAN bus system, the automotive traction battery modules of each traction battery module group a group-specific automotive CAN bus system is connected, the number of traction battery module groups depending on the electrical target energy of the electrical consumer, and the group-specific automotive CAN bus systems are connected to a higher-level control device. This further development is particularly preferred in order to provide a ship voltage supply system using automobile traction battery modules and automobile CAN bus systems, which provides an electrical consumer of the ship with the desired electrical target voltage and electrical target energy.
    The power station voltage supply system according to the invention is defined in claim 8.
    Preferred developments of the invention result from the dependent claims and the following description. Exemplary embodiments of the invention are explained in more detail with reference to the drawing, without being restricted to this. It shows:
    1 shows a first ship voltage supply system according to the invention; and FIG. 2 shows a second ship voltage supply system according to the invention.
    The invention relates to a ship voltage supply system 10 for supplying an electrical consumer of a ship with an electrical target voltage and an electrical target energy.
    CH 713 423 A2 The invention also relates to a power plant voltage supply system for supplying an electrical consumer of a power plant with a target electrical voltage and a target electrical energy. The invention is described below with reference to ship voltage supply systems. However, the inventions also apply to power plant voltage supply systems.
    [0012] The ship voltage supply system 10 has a plurality of automotive traction battery modules 11, each automotive traction battery module 11 having an actual electrical voltage and an electrical actual energy.
    The automotive traction battery modules 11 are dependent on the target electrical voltage, the actual electrical voltage, the target electrical energy and the actual electrical energy to several traction battery module sub-groups in series and / or to at least one traction battery module group connected in a parallel connection.
    Fig. 1 shows a first embodiment of an inventive marine power supply system 10 with a plurality of automotive traction battery modules 11, with five such automotive traction battery modules 11 being shown by way of example in Fig. 1. All automobile traction battery modules 11 are connected in the sense of parallel connections to at least one traction battery module group, namely in FIG. 1 to two traction battery module groups 12a, 12b, with the traction battery module group 12a in FIG. 1 three automotive traction battery modules 11 and the traction battery module Group 12b comprises two automotive traction battery modules 11.
    In Fig. 1, not only are the automotive traction battery modules 11 of the respective traction battery module group 12a, 12b each connected in parallel to one another, rather the traction battery module groups 12a, 12b are also connected in parallel to one another, so that all the automotive traction battery modules 11 of the traction battery module -Groups 12a, 12b are connected in the sense of a parallel connection to a common voltage supply line 18, via which at least one electrical consumer of the ship, in particular an electrical machine serving as a drive source, can be supplied with the desired target voltage and the desired target energy.
    In Fig. 1, the actual voltage of the automotive traction battery modules 11 corresponds to the electrical target voltage of the electrical load, the number of parallel connected automotive traction battery modules 11 depends on the required electrical target energy.
    The control of the automotive traction battery modules 11 takes place via automotive CAN bus systems. Such automotive CAN bus systems have a limited control signal capacity. Therefore, the automotive traction battery modules 11 of each traction battery module group 12a, 12b are each controlled via a group-specific automotive CAN bus system 13a, 13b, namely the automotive traction battery modules 11 of the traction battery module group 12a via the automotive CAN bus system 13a and the automotive Traction battery modules 11 of the traction battery module group 12b via the automotive CAN bus systems 13b. Bus controllers 14a, 14b coordinate the transmission of the control signals via the respective automotive CAN bus system 13a, 13b, the automotive CAN bus systems 13a, 13b and the bus controllers 14a, 14b being connected to a higher-level bus system 15 in order to to exchange this superordinate bus system 15 with a superordinate control device 16.
    Another ship voltage supply system 10 according to the invention is shown in FIG. 2. In the ship voltage supply system 10 of FIG. 2, there are a total of twelve automobile-automotive traction battery modules 11, four of which are connected to a traction battery module group 12a, 12b, 12c are. Within each traction battery module group 12a, 12b and 12c, two of the four automobile traction battery modules 11 are connected in the sense of a series connection to traction battery module sub-groups 17a, 17b and 17c, the traction battery module sub-groups 17a, 17b and 17c in the sense of a parallel connection are connected to the respective traction battery module group 12a, 12b or 12c.
    In Fig. 2, the actual electrical voltage of the automotive traction battery modules 11 is smaller than the target electrical voltage of the electrical consumer of the ship, the number of connected in a row and to a traction battery module sub-group 17a, 17b and 17b interconnected automotive traction battery modules 11a depends on the ratio of the actual voltage to the target voltage.
    The number of traction battery module groups 12a, 12b, 12c depends on the ratio of the actual energy to the required target energy. The traction battery module groups 12a, 12b, 12c connected in parallel are connected to a common voltage supply line 18.
    Each traction battery module group 12a, 12b, 12c in turn interacts with a group-specific automobile CAN bus system 13a, 13b or 13c, in this regard bus controllers 14a, 14b, 14c being coupled to a higher-level bus system 15 in order to communicate with the higher-level control device 16 to communicate. The number of automotive traction battery modules 11 per traction battery module group 12a, 12b, 12c in turn depends on the control signal capacity of the automotive CAN bus system.
    The invention allows using a known and available automotive traction battery modules 11 and known and available automotive CAN bus systems 13, 15 to build an electrical ship voltage supply system 10 to at least one electrical consumer of a ship with a desired electrical destination3
    CH 713 423 A2
    To supply voltage and a desired electrical target energy, so that the ship voltage supply system 10 can be constructed inexpensively and reliably using assemblies known per se. The actual electrical energy of known automobile traction battery modules 11 is between 10 kWh and 100 kWh, in particular in the order of 20 kWh. The target electrical energy of the ship's electrical consumer is typically greater than 1000 kWh, typically on the order of several MWh.
    In the parallel arrangements of the automotive traction battery modules 11 (see Fig. 1) and in the parallel arrangements of series-connected automotive traction battery modules 11 or in the parallel arrangements of traction battery module sub-groups 17 (see Fig. 2) results very high redundancy. If an error occurs in an automotive traction battery module 11 and this has to be switched off for protection as a result, the electrical voltage supply can be maintained. With a correspondingly large number of parallel automotive traction battery modules 11 or parallel traction battery module subgroups 17, a power or energy penalty is low. Such an error is recognized via the automotive CAN bus system. The failure of automotive traction battery modules 11 is reported accordingly to a higher-level control system.
